Probability density functions (pdfs) and probability mass functions are denoted by lowercase letters, e.g. , or . Cumulative distribution functions (cdfs) are denoted by uppercase letters, e.g. , or . In particular, the pdf of the standard normal distribution is denoted by , and its cdf by .
Most of the sources are from the 1990s. Of the 20 million words in the corpus, about one-third (~6,750,000 words) come from transcripts of spoken Spanish: conversations, interviews, lectures, sermons, press conferences, sports broadcasts, and so on.

The score of 20 for a K is the highest known point value for any letter in any Scrabble score distribution worldwide. The fourth distribution, which uses U instead of V, and includes Y, is as follows: [ 34 ] 2 blank tiles (scoring 0 points) 1 point: E ×10, A ×9, I ×9, S ×9, T ×9, U ×9. 2 points: M ×6, N ×6, O ×6, R ×6.
The phoneme /ʎ/ is distinguished from /ʝ/ only in some areas of Spain (mostly northern and rural) and South America (mostly highland).
